Harry Gewanter, M.D., FAAP, FACR

Dr. Gewanter is a pediatrician and pediatric rheumatologist who has practiced in Richmond, Virginia for almost three decades.  A graduate of Duke University and Wayne State University Medical School, he received his general pediatric and pediatric rheumatology training at the University of Rochester.  He has been actively involved in national, state and local professional, community, and disability organizations.  These have included the Virginia Board for People with Disabilities, the national American Academy of Pediatrics Committee on Children with Disabilities, a variety of volunteer positions within the national and Mid-Atlantic Region Arthritis Foundation, and the first Walter E. Bundy, Jr Clinical Professor of Community Pediatrics at the Medical College of Virginia.  As a result of both his personal and professional interests and experiences, his practice has evolved over the years into primarily caring for children and youth with disabilities and special health care needs.

Beyond personally advocating for his patients, Gewanter helped co-found Medical Home Plus, Inc., a 501(c)3 organization that provides information, support and referrals for families of children and youth with any disability.  One of its primary activities is working with families who are having difficulties working with their school system.  Since three of his four children had IEPs, he lived through the many challenges parents and children with disabilities or chronic health problems face within the public school system.  These experiences have resulted in a desire to help other families undergo fewer difficulties than those of his children and family.
